Like Mother(-in-Law) Like Daughter? Influence of the Older Generation’s Fertility Behaviours on Women’s Desired Family Size in Bihar,India

This paper investigates the associations between preferred family size of women in rural Bihar, India and the fertility behaviours of their mother and mother-in-law. Scheduled interviews of 440 pairs of married women aged 16–34 years and their mothers-in-law were conducted in 2011. Preferred family size is first measured by Coombs scale, allowing us to capture latent desired number of children and then categorized into three categories (low, medium and high). Women’s preferred family size is estimated using ordered logistic regression. We find that the family size preferences are not associated with mother’s fertility but with mother’s education. Mother-in-law’s desired number of grandchildren is positively associated with women’s preferred family size. However, when the woman has higher education than her mother-in-law, her preferred family size gets smaller, suggesting that education provides women with greater autonomy in their decision-making on childbearing.     

Analyzing Social Media Engagement and its Effect on Online Product Purchase Decision Behavior

The continuous progress of society in using online resources has given opportunity to many business executives to utilize social media for their brand promotion or recognition. Organizations utilize social media sites like Twitter, Facebook, LinkedIn, Flicker, Google Plus, and YouTube to promote their product, service, or brand worldwide. Increase of consumer engagement in online social activities has forced companies to integrate social media factors into their marketing strategy. The objective of this study is to find the important factors on which the online purchasing decision depends, based on the personality types of consumers and their attitude toward social media with brand perception.     

Evidence for a curvilinear relationship between abusive supervision and creativity in South Korea

Applying activation theory, this study examined the possibility of a curvilinear relationship between abusive supervision and employee creativity. Using survey responses of 203 subordinate–supervisor dyads in South Korea, hierarchical regression analyses demonstrated a curvilinear (inverted U-shaped) relationship between a supervisor's abusive behaviors and an employee's creative performance. Specifically, employees exhibited more creativity when abusive supervision was at a moderate level rather than at very low or very high levels. Implications for theory and practice are discussed.     

Connecting older grandmothers raising grandchildren with community resources improves family resiliency,social support,and caregiver self-efficacy

Custodial grandparenting can be especially challenging for older grandmothers facing age specific issues. Kinship navigator programs are social service delivery programs intended to inform grandparents and other relatives raising children about available resources and services, provide information specific to their individual needs, and help families navigate service systems. Our study utilizes self-report data from one kinship navigator federal demonstration project, which used a randomized control trial, to examine demographic characteristics for grandmothers under and over 55 years of age, whether grandmother caregivers (≥55 years) improve family resilience, social support, and caregiver self-efficacy, and which interventions improved outcomes for grandmothers (≥55 years). Each participant was randomly assigned to one of four groups: Usual Care (traditional child welfare services), Standard Care (family support and case management), Peer-to-Peer Care Only, and Full Kin Tech Care (peer navigators with computer access and interdisciplinary team). Thirty-nine percent of grandmothers (55-75 years) were mostly living in poverty, predominantly Caucasian, with 36% identifying as African American/Black, with at least one to two children at home. Repeated-measures ANOVAs for each subscale showed statistically significant within- and between-group differences for Family Functioning, Social Supports, Concrete Supports, Child Development, and Nurturing and Attachment, with the exception of Usual Care, which showed a decline in protective factors consistently across subscales. Future research with kinship families could qualitatively examine the experiences for older women in navigator programs and replication of kinship navigator programs could build capacity in data collection and maintenance systems to gain better perspective about how systems of care impact families.     

Improved estimator of population total in PPS sampling

In this paper, we have considered an estimation of the population total Y of the study variable y, making use of information on an auxiliary variable x. A class of estimators for the population total Y using transformation on both the variables study as well as auxiliary has been suggested based on the probability proportional to size with replacement (PPSWR). In addition to many the usual PPS estimator, Reddy and Rao's (1977) estimator and Srivenkataramana and Tracy's (1979, 1984, 1986) estimators are shown to be members of the proposed class of estimators. The variance of the proposed class of estimators has been obtained. In particular, the properties of 75 estimators based on different known population parameters of the study as well as auxiliary variables have been derived from the proposed class of estimators. In support of the present study, numerical illustrations are given.     

Graph based isomorph-free generation of two-level regular fractional factorial designs

We provide a new necessary and sufficient check for testing the isomorphism of two 2-level regular fractional factorial designs. The approach is based on modeling fractional factorial designs as bipartite graphs. We employ an efficient canonical graph labeling approach to compare two designs for isomorphism. We then improve upon the existing non-isomorphic fractional factorial design generation algorithm by reducing the number of candidate designs from which isomorphs need to be removed. Not only does our method generate non-isomorphic designs much faster, it is also able to generate designs with run sizes of 2048 and 4096 runs, which were not generated by the existing methods.     

Management of nature-based goods and services provisioning from the urban common: a pan-European perspective

The role of the urban common (i.e. shared space and resources) in sustainable provisioning of goods and services to city dwellers is discussed in this paper. Focusing on tree-based green infrastructure, the study scope includes three categories of provisioning (woody biomass, food/fibre, and non-timber forest products, i.e. NTFPs), alongside three categories of supporting services (fresh water replenishment, soil nutrient restoration, building preservation). As a first step, prospects of utilizing the urban common as facilitator of nature-based solution to the earmarked provisioning services are evaluated through dedicated literature survey and expert elicitation on perceived impact of environmental change triggers and management interventions (planning and/or governance). This is followed by a structured review of the state of affairs in four European cities (London, Amsterdam, Sofia, Ljubljana), representing different macro-geographical regions with distinct socio-economic drivers in managing these provisioning services. The pan-European expert elicitation exercise noted active management of the urban common as positively impacting on the performance of the majority of provisioning services, while environmental change impacts were found to be overriding and adversely influencing the provisioning of material resources (mainly NTFPs and woody biomass). The four-city case study highlighted some regional peculiarities in connecting the city dwellers to the urban common and identified the need to overcome socio-cultural barriers for enhancing pan-European best practice sharing in the management of goods and services provisioning. This is deemed essential to pave way for an emerging perspective on sustainable utilization of the urban common as an enabler for nature-based solution, making it fit for purpose in meeting the astronomical demands of future urban living.

     

Bias corrected empirical Bayes confidence intervals for the selected mean

Empirical Bayes (EB) methods are very useful for post selection inference. Following Datta et al. (2002 Datta, G. S., M. Ghosh, D. D. Smith, and P. Lahiri. 2002. On an asymptotic theory of conditional and unconditional coverage probabilities of empirical Bayes confidence intervals. Scandinavian Journal of Statistics 29:139–52.[Crossref], [Web of Science ®] , [Google Scholar]), we construct EB confidence intervals for the selected population mean. The EB intervals are adjusted to achieve the target coverage probabilities asymptotically up to the second order. Both unconditional coverage probabilities of EB intervals and corresponding probabilities conditional on ancillary statistics are found.
